Assuming the Chosen One does not kill T-Ray in the process of recovering the Highwayman, T-Ray can be contracted to perform upgrades on the car. Initially the only upgrade available is increased trunk space for $500 ($300 if the Chosen passes a Barter check), however, upon completion of the game's main story line one may opt to have T-Ray install grav plates to significantly reduce the car's fuel consumption.

If slept with to recover the car, and seduced again for the upgrade, he will say he "just gave you [the female Chosen One] sweet love five minutes ago". This is a reference to Chef, a character from the show South Park, during the episode, 'Weight Gain 4000'.
